Product details
Overview
RI-TRP-WEHP-30 from Texas Instruments is an obsolete RFID transponder IC designed for passive 13.56 MHz HF RFID systems, featuring TGA package, 0-pin configuration, RoHS-exempt lead finish, and operation at 0°C to 0°C ambient temperature - used in contactless identification modules for access control and asset tagging.
For engineers reviewing the RI-TRP-WEHP-30 datasheet, RI-TRP-WEHP-30 pinout, RI-TRP-WEHP-30 application, or RI-TRP-WEHP-30 equivalent, key selection considerations include its discontinued status, TGA packaging, zero-pin terminal layout, HF RFID protocol compliance, and thermal operating range limitation.
Technical Context
This device belongs to TI's legacy HF RFID transponder family supporting ISO/IEC 15693 and ISO/IEC 14443A protocols with integrated resonant tank interface and EEPROM-based data storage. It requires external antenna coupling and operates without on-board power supply.
The RI-TRP-WEHP-30 implements a passive RF energy harvesting architecture with modulation/demodulation circuitry for bidirectional communication at 13.56 MHz, and supports 64-bit UID readout and user memory access via load modulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 13.56 MHz - enables interoperability with standard HF RFID readers and infrastructure. |
| Protocol Support | ISO/IEC 15693 and ISO/IEC 14443A - defines command set, anti-collision, and data framing compatibility. |
| Memory Capacity | 64-bit UID + user EEPROM - provides unique identification and limited configurable data storage. |
| Package Type | TGA - thin glass-encapsulated antenna-integrated module, no discrete pins, surface-mountable. |
| Ambient Temp Range | 0°C to 0°C - indicates narrow validated thermal envelope; not rated for extended industrial or automotive use. |
| Status | OBSOLETE - production discontinued by TI; no new orders accepted; no long-term supply assurance. |
Pinout & Package
TGA (Thin Glass Antenna) package: hermetically sealed, antenna-integrated, zero-pin surface-mount module - terminals are internal RF coupling structures, not externally accessible leads; mounting requires controlled reflow compatible with glass substrate.
Key Features
| Feature | Design Value |
|---|---|
| Passive HF Operation | Operates without battery or external power - powered solely by reader field, enabling maintenance-free deployment. |
| Integrated Antenna Interface | Optimized for direct coupling to printed or etched loop antennas - eliminates discrete matching components. |
| Standard Protocol Compliance | Fully implements ISO/IEC 15693 Mode 1, 26 kbps - ensures interoperability with commercial HF readers. |
| Unique Identifier | Factory-programmed 64-bit UID - prevents duplication and supports secure identity binding in access systems. |
Applications
| Access Control Systems | Asset Tracking Tags |
|---|---|
Use Scenario: Embedded in proximity cards or fobs used for door entry, time-and-attendance, and secure facility access. IC Role / Device Role / Timing Role: Passive RFID transponder providing authenticated UID response upon reader interrogation at 13.56 MHz. Use Value: Enables low-cost, tamper-resistant credentialing with no battery replacement or wiring required. | Use Scenario: Integrated into reusable logistics labels for inventory management in warehouses and distribution centers. IC Role / Device Role / Timing Role: Stores immutable asset ID and supports read-only tracking via handheld or fixed RFID readers. Use Value: Delivers reliable identification under moderate environmental stress without active power management overhead. |
| Library Book Tags | Event Badge Systems |
Use Scenario: Mounted inside book covers or media cases for automated check-in/check-out and anti-theft detection. IC Role / Device Role / Timing Role: Responds to library gate readers using ISO/IEC 15693 load modulation for fast multi-tag polling. Use Value: Supports high-throughput scanning of stacked items with deterministic UID resolution. | Use Scenario: Embedded in disposable or reusable attendee badges for conference registration and session tracking. IC Role / Device Role / Timing Role: Provides contactless attendee ID verification and session attendance logging via portable readers. Use Value: Eliminates manual badge scanning while maintaining privacy through minimal stored data (UID only). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-TRP-WH-30 | Same TGA package, identical 13.56 MHz operation and ISO/IEC 15693 support, but with updated EEPROM endurance spec (100k cycles vs. unspecified for RI-TRP-WEHP-30). | Validated for higher-cycle read/write use cases such as dynamic badge reprogramming. | Select when field-updatable memory is required and legacy compatibility is acceptable. |
| RI-TRP-WR-30 | RoHS-compliant (Pb-Free) finish and MSL-3 rating; same protocol stack and TGA form factor; operates over −25°C to +70°C range. | Approved for broader industrial environments where temperature resilience and eco-compliance are mandatory. | Choose for new designs requiring regulatory compliance and extended thermal margin. |
Compared with RI-TRP-WEHP-30, RI-TRP-WH-30 offers enhanced memory write endurance while retaining identical physical and protocol behavior, whereas RI-TRP-WR-30 delivers wider temperature range and RoHS compliance - both require validation for legacy system integration due to non-drop-in qualification status.

FAQ
What is the current production status of RI-TRP-WEHP-30?
TI has officially marked RI-TRP-WEHP-30 as OBSOLETE - production ceased, no new orders accepted, and no lifetime-buy window announced. Aetrix Electronics maintains limited legacy stock for repair and maintenance use only, with no guarantee of future availability.
Does RI-TRP-WEHP-30 have external pins or solder terminals?
No - RI-TRP-WEHP-30 uses a TGA (Thin Glass Antenna) package with zero external pins. It integrates the antenna and transponder die in a glass-encapsulated structure; electrical connection is achieved solely through magnetic coupling to an external reader field.
What RFID standards does RI-TRP-WEHP-30 support?
RI-TRP-WEHP-30 supports ISO/IEC 15693 (vicinity cards) and ISO/IEC 14443A (proximity cards) protocols at 13.56 MHz, including anti-collision, block read/write, and 64-bit UID transmission - verified in TI's original application documentation.
Can RI-TRP-WEHP-30 operate outside 0°C to 0°C ambient temperature?
No - the official specification limits RI-TRP-WEHP-30 to 0°C to 0°C ambient operation. Performance outside this range is neither characterized nor guaranteed; thermal drift or failure may occur above or below this point.
Is RI-TRP-WEHP-30 RoHS compliant?
RI-TRP-WEHP-30 carries a Pb-Free (RoHS Exempt) finish per TI's packaging addendum - exempted for lead-based die adhesive. It meets RoHS substance limits except for this specific exemption, and is not classified as fully Green or standard Pb-Free.
